Watch Oxford indie-folk band Stornoway perform on top of a camper van at
Glastonbury music festival.

STORNOWAY: It’s usually up to me [Brian], I write most of the songs. I come up with the idea and bring it to the rest of the band, alongside some dodgy demo, and then we arrange it, through the process of recording it and trying different things out and end up with something that’s hopefully a bit interesting. Occasionally it's a bit more collaborative, and it will be a combination of riffs from one person and lyrics from another.
